DEFLECTOR.

Application filed September 23, 1927. Serial No. 221,582.

My invention relates to deflectors which may be employed with coalbreakers and/or cleaners of the Bradford type, such as illustrated inthe patent of- Borton and Hillel, N 0. 1,086,129, dated February 3,1914, or the patent of Hiller, No. 1,322,568, dated November 25, 1919.

Inthe operation of these and similar structures, coal or other materialto be cleaned and broken is fed into a rotating drum forming thebreaker. This drum is usually constructed of peripherally disposedscreen plates which carry deflector blades serving to feed the materialforward as it is carried round by the moving drum. In some instances,so-

called tailings' deflectors are employed-with breakers of this type forcooperation with a tailing plow or plows; the action of which serves togovern the time the material is'retained in the breaker, as well ascontrolling the rate of discharge of the tailings by such plow. j Myimproved deflector is ofthe universal type and may be employed as a feeddeflector in breaker structures of the type illustrated in the Bortonand I-Iiller patent, referred to, or as the tailings deflectorin abreaker structure of the type illustrated in the patent of Hiller,before referred to; I

These and other features of my invention are more fully describedhereinafter; reference being had to the accompanying drawings, in which:

Fi ure 1, isa View showing a portion of a coal breaker and the manner inwhich my improveddeflector'blade may be employed therewith. i a

Fig. 2, is a similar view showing my improved structure employed as atailings deflector. a

Fig. 3, is-a planview'of my improved deflector blade. F I y i Fig. 4, isa sectional View on the line IV IV, Fig. 3, and" Fig. '5, is a sideelevation.- My improveddeflector comprises a blade 1, which may have oneof its ends tapered as indicated at 1*;such blade having itsbodyslightly enlarged intermediate its ends,as indicated at 1*. Theenlarged portion of the blade is provided with a through passage 1",

V for the reception of an anchoring bolt 2'; such anchoring bolt beingintended to support the deflector in its desired position in the cage ordrum of the breaker relatively to the length of the same. The base ofthe blade is provided with flanges 3, disposed on opposite sides of thesame, which flanges may be substantially identical in contour, and. suchflanged portion is provided with a curved slot 4; the walls of which maybe on the arcs of circles struck from the axis of the anchor-' ing bolt2. The slot 4 is provided for the reception of a bolt 5, employed forholding the blade in adjusted positions of angularity with respect tothe anchoring bolt2 securing the same to the drum.

The bolt 5 which passes through the slot 4 is designed tomaintain thedeflector blade at the desired angle,and in practice such bolt passesthrough an aperture of the screen wall. Owing to its function ofdiverting the material carried round by the drum, the frictional holddeveloped by a nut secured to. said bolt will not maintain the deflectorblade in the desired position, and inthe structure il lustrated in theHiller patent, for instance,

the end of the blade furthest from the relatively pivotal'connection hasbeen provided with apertured lugs for the reception of bolts, which passthrough and are clamped to the screen plates forming the drum structure,for the purpose of holding such-deflector blade in its adjustedpositions;

In the present arrangement, the curved slot 4, formed in the flangedportions 3, is flanked by raised wall portions 6, the inner edges ofwhich are angularly recessed at 6 in such relation as to form seats toreceive thev polygonal head 5 of the bolt 5, (in the pres ent instancesquare) employed for holding the deflector blade in adjusted positions,and p by preference a number of oppositely disposed recesses may beemployed so as to provides. plurality of seats for thehead 5 of the bolt5 and permit a; relatively wide range I of adjustmentfor said deflectorblade. I

The bodyof the deflector blade, is recessed.

. or transversely apertured at 7, above the slot 4, to permitlifting ofthe head 5 of the bolt 5 clear of the wall portions 6 providing the inn'seats'for such bolthead, when it is desired to shift the blade on thepivot formed by the anchoring bolt2, with respectto said bolt 5; the nut5 ofthe latterbeing backed off to permit such lifting.

In practice, the deflector blade is placed in the desired positionoonthe screen plate wall of the breaker drum, and theanchoring bolt 2 setin place; its position determining the axis upon which the deflectorblade may be moved for the desired angular adjustments. The belt 5 maythen be placed in position; passing through an aperture in a 7 screenplate, and its head 5 placed in one of the seats formed by the recessedwalls flankingthe curved slot 4; the seat employed being the one thatwill give the blade in its finally secured position the desiredangularity with respect to the wall of the breaker drum. Should a changein angularity be desired, the nut 53 holding the bolt 5 may be backedoff to an extentsufficient to permit the head of the bolt to be liftedfrom its seat and into the opening 7 whereby the deflector blade maybemoved on the pivot formed by the anchoring bolt 2, until a fresh seatis in registry beneath the head 5 of such bolt Further adjustment of thedeflector blade may be effected by shifting the position of the bolt 5with respect to the bolt 2. i

I claim:

1. The combination, with the apertured 'wall of a breaker drum, of adeflector blade throughan aperture of the breaker drum wall; and arecessed lug flanking said slot and forming seats for the reception ofthe head of the retaining" bolt whereby the latter vmay reta'in saidblade in adjusted positions;

said blade having a transverse opening above said slotinto which thehead of said retaining bolt may be displaced from its seat when movingsaid blade on the anchoring bolt to change the angular position thereof.

2. A deflector blade adapted to be posi tioned wit-h respect to. theapertured wall of a breaker drum, a pivotal anchoring bolt carried bysaid blade and passing through said apertured wall, a retaining boltcarried by said wall adjacent the opposite end of said blade; the latterhaving a foot with a slotted portion permitting angular adjustment ofthe blade with respect to'said retaining bolt, and

a seat adjacent said slotted portion for the reception of the head ofthe retaining bolt whereby the latter may retain said blade in adjustedpositions; said blade having a transverse opening above said slot intowhich the head of said retaining bolt may be displaced from its seatwhen moving said blade on the anchoring bolt to change the angularposition thereof.

bolt, a foot portion formed by lateral flanges disposed on oppositesides of said blade; said flanges being provided with a slot throughwhich a retaining bolt may be passed whereby angular adjustment of theblade on said anchoring bolt acting as a pivot may be effected, andraised portions flanking saidslot and having oppositely disposedrecesses forming seats for the head of said retaining bolt; said bladehaving a transverse opening abovesaid slot into which the head of saidretaining bolt may be displaced when effecting angular adjustment of theblade.

- l. As a new article of manufacture, a deflector blade adapted to besupported by the wall'of a breaker drum and having an open ing for thepassage of an anchoring bolt securing said blade to said wall with anangular recess in the upper edge of the blade receiving the head of saidanchoring bolt;

said blade being movably mounted on the anchoring bolt, afoot portionformed by lat-- eral flanges disposed on opposite sides of the lade;said flanges being provided with a slot through which a retaining boltmay be passed whereby angularadjustment of the blade on said anchoringboltacting as a pivot'may be effected, and a recessed port-ion flankingsaid J slot and forming a plurality of seats for the head of saldretaining bolt; said blade hav ing a transverse opening above said slotinto.

' which the head of the retaining bolt may be displaced when effectingangular adjustment of the blade.

5. As a new article ofvmanufacture, a deflector blade adapted to beSupported by the wall of a breaker drum and having an opening for thepassage of an anchoring bolt securing said blade to said well; saidblade being movable on said anchoring boltrand having a slotted portionadjacent its opposite end through which a retaining boltmay be passedwhereby angular adjustment of the blade on said anchoring bolt acting asa pivot may be effected, and a raised portion flanking said slot andhaving recesses formingseats for the head of said retaining bolt ;saidblade having a transverse opening above 5 said In witness whereof I havesigned this specification.
